Oct 7, 2015

$x = - 1$

#### Explanation:

Given
$\textcolor{w h i t e}{\text{XXX}} 4 \sqrt{x + 2} = 4$
Divide both sides by $4$
$\textcolor{w h i t e}{\text{XXX}} \sqrt{x + 2} = 1$
Square both sides
$\textcolor{w h i t e}{\text{XXX}} x + 2 = 1$
Subtract $2$ from both sides
$\textcolor{w h i t e}{\text{XXX}} x = - 1$
